Wheel scraper



Patented Nov, 18, V14930 FRANK T. ZERWIG, OF STE. GENEVIEVE, MISSOURI WHEEL SCRAI'ER Application led September 25, 1929.k Serial No. 395,110.

The present invention is directed to improvements in wheel Scrapers.

The primary object of the invention is to provide a device of this character so constructed that it can be conveniently attached to a tractor so that the wheels thereof will be maintained free from dirt which, as iswell known, collects on the rims of tractor wheels and retards the effectiveness of the calks upon the wheels. i Q

Another object of the invention is toy provide a device of this character so constructed that it will be yieldably held in contact with the wheel rim and is disposed between the cleats thereof so that dirt or mud collecting upon the wheel will be effectively scraped therefrom.

Another object of the invention is to provide a device of this character which is simple in construction, easy to install, and one which is durable and can be manufactured at a minimum cost. f f

Vith these'and other objects in view, .this

invention resides in the novel features of construction, formation, and combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which:

Figure l is a fragmentary side view of a drive wheel ofa tractor showing the device in position thereon.

Figure 2 is a Vsectional View on the line 2-2 ofvFigure l.

Figure 3 is a sectional view on the 4line 3 3 of Figure l. f

Figure 4 is ai sectional viewon the line 4 4 of Figure l.

Referring to the drawing, 1 designates a portion of a drive wheelv of a conventional.

form. of tractor, the rim V2 of which is provided with laterally spaced cleats 3.

6 which are secured toV the frame of thetractor, as customary. Avn keye bolt 7Vis passed through the fender 4 andbrac'e 6 and has pivotally connected thereto the eye S'of theV arm 9', said arm having at one end thereof, a loop 9 and to whichis bolted the scraping blade 10, said blade having its lower edge arranged for movementin the space vbetween the cleats 3, as clearly shown in' Figure 250f n:

the drawing. In order to hold the scraping blade l0 in yielding Contact with the rini'2, a. U-bolt l1 is provided, the arms of which are passed through the brace 5 and fender 4, '35

said arms being encircled by springs l2 which bear upon ya Aplate 13 having openings 14 therein for slidably engaging the arms of the bolt. The arm 9 is engaged between thebight portion of the bolt l1 and plate 13, and it willA be obvious that the springs 12 will tend to.

urge the arm 9 downwardly inorder that the' scraping edgefof the bladel() will be held in yielding Contact with the rim 2 so that during movement of the wheel, the dirt which may collect upon the rim thereof and'y be` tween the cleats will be effectively scraped therefrom. It will thus be seen that any their Ventire depth, thus materially increas ing the) traction power thereof.

From the foregoing it is ,tlfioitghtv that the 75 operation, and many advantages of the lhere-- in described invention will be apparent to 'K those skilled inthe art without further de Vscription,v and it will be understood that various-changes inthe size, shape, proportion, 570 v and minor Vdetails of construction may be resorted to without departing from the spirit or sacrilicing .of the advantages offthe invention. Y

W hat is claimed is.: r y,

The combinationy with a tractiony wheel, f and braces at the side thereof having portions extendingy across the rim; ofthewheel in' spaced relatonjthereto, of an arm disposed betweenthe rim of the wheel' and the '90. overhangin'g portions of the bracesA and piva The fender 4 vis supported by braces 5 and oted atfoneend to one of thebraces, and having its opposite end curved outwardly,

Vthence inwardly, a scraping blade attached v to the recurved end ofthe armV and engaging 95 the arms of the U-bolt and engaging the outer side of the pvoted arm, and springs on the arms of the U-bolt between the brace and plate to yeldably hold the scraper blade in Contact with the rim of thev traction Wheel.

In testimony whereof I aflx my signature.
